TRAIN WHEEL Meaning and
Definition
-
The term "train wheel" refers to a circular component that is an essential part of a train's locomotion system. It is designed specifically to facilitate the smooth movement of the train on the tracks. Train wheels are typically made of durable and sturdy materials, such as steel or iron, to withstand the immense weight and pressure exerted on them as the train travels at high speeds.
Train wheels possess a distinct tread that allows them to maintain traction with the rails, preventing slippage and ensuring stability. The tread also helps reduce friction and wear on both the wheels and the tracks, enhancing the overall efficiency and longevity of the system. Train wheels are equipped with flanges, which are raised edges placed on the inner side of the wheels. These flanges serve a crucial role in guiding the train as it traverses curves or turns, preventing derailment by keeping the wheels securely on track.
Another important aspect of train wheels is their size and shape, as they may vary depending on the specific type of train or location. For instance, locomotives designed to operate on standard gauge tracks usually have larger wheels compared to those used for narrower or broader gauges. Overall, train wheels play a vital role in the safe and reliable functioning of a train, enabling it to transport passengers or cargo across vast distances in a smooth and controlled manner.
Etymology of TRAIN WHEEL
The word "train wheel" comes from Old English and has evolved over time. The term "train" is derived from the Old French word "trahiner", meaning "to pull or draw", which can be traced back to the Latin word "traginare", meaning "to pull or drag". The word "wheel" can be traced back to the Old English word "hweol", which is related to the Old Norse word "hjol" and the Gothic word "hweila". The combination of these words, "train" and "wheel", refers to the wheels used for pulling or moving a train or vehicle.
